My wife has restricted me to a wall mount for my surround speakers that extends 5.9 inches from the wall, so the speakers could be a bit bigger than that, they just can't fall off of course. I curently have terrible junk speakers. They were surround speakers that came with a rack system I got in 1990 before having any money to get into a better sounding solution. Here's a picture of my limitations for mounting: So, I'm looking for the best speakers that can fit on a base of 5.9". Does anyone have any idea? My front and center speakers are Paradigm Reference. Thanks for the help!
